Abstract
<B>"MéTODO E APARELHO PARA AJUSTE ADAPTATIVO DO SINAL DE SONDAGEM DE USUáRIO<D> Um método e aparelho para ajustar adaptativamente a potência de um sinal de sondagem a ser transmitido pelo equipamento do usuário, com base em uma característica dos sinais recebidos e constantes do sistema, de modo a aumentar a probabilidade de que o sinal de sondagem será detectado pelo equipamento do sistema de um sistema de comunicação. O desvio Doppler de um sinal piloto recebido é derivado e um parâmetro de ajuste é calculado com base no desvio Doppler, no intervalo de tempo entre transmissões de sondas sucessivas e nas constantes do sistema. O parâmetro de ajuste é aplicado ao sinal de sondagem a ser transmitido para compensar pelos efeitos de desvanecimento a ser experimentado pelo sinal de sondagem a ser transmitido.
